I have the pressure cap thing, it's fine for what it is but I don't have extensive mokka pot collection to compare it against. What's the new pressure valve look like?
edit I googled it:
Seems like a better system, but I don't really drink enough mokka pot to try the upgrade.
The lid is very simple and has a minimum of moving parts, but it's quite unreliable, often going off if you knock the brikka, or going off then turning on again..etc.
What I want is a brikka sized tamper...
